| 摘 要： | 建立了带推力矢量的涡扇发动机数学模型。结合某型涡扇发动机研究了矢量喷管偏转对发动机工作和性能的影响,研究结果表明,矢量喷管偏转时,在一定条件下,发动机低压转子共同工作线向喘振边界移动,而高压转子共同工作线不发生变化,发动机总推力是增大的。但当将矢量喷管偏转与喉部面积放大相结合,可使发动机保持原工作状态不变,而发动机总推力却随着几何矢量角的增大而减小。

| Abstract: | A mathematical model of turbofan engine with thrust vector control was established.By employing certain turbofan engine as a sample,the effects of vector thrust control on turbofan engine performance and co-operation were studied.Under certain conditions,the results show that the operation line of low-pressure spool moves towards the surge margin when the thrust vector nozzle deflected.But the operation line of high-pressure spool does not change,and the total thrust increases.When combining deflection of the thrust vector nozzle with increasing the nozzle area,the original operation situation of the turbofan engine can be kept.But the total thrust of the turbofan engine is decreased. |
